Hi all, I recently purchased a 2007 Nissan Pathfinder SE with 70K miles on it. It looks and runs great, and I am very happy with it. However, looking for reviews I found many concerns regarding reliability, and some common problems like radiotor fluids leaking into the transmission, and stuff like that. I am starting to get worried I made a bad decision. Always been a fan of japanese cars for their quality and reliabilty, so any opinions of the other members will help. Cheers.
